Case report: Antidromic atrioventricular reentrant tachycardia and underlying Ebstein anomaly.

Multiple accessory pathways (APs) can develop in patients with Ebstein anomaly. Rarely, these APs can participate in antidromic atrioventricular reentrant tachycardia (AVRT) which can be life-threatening and requires unique considerations for acute management and ultimate ablation. These considerations are discussed herein.

When Recurring Infections Mask an Atypical Presentation of Inflammatory Bowel Disease (IBD): A Re-Visitation and Literature Review.

Pyoderma gangrenosum (PG) is an uncommon and severe extra-intestinal manifestation (EIM) of inflammatory bowel disease (IBD). Head or scalp involvement in this condition is exceedingly rare. Approximately one-third of presentations can be precipitated by skin trauma or infection, a phenomenon known as pathergy. These ulcers develop acutely, do not necessarily correlate with IBD activity, and can precede IBD diagnosis. Here, we present an atypical presentation of PG that became a cornerstone finding in the subsequent diagnosis of IBD.
